I can't understand ur question properly but..........there are four zones divided on the basis of water saturation

  1. Saturation zone :- It is the zone beneath the earth surface where 100% of saturation takes place.
  2. Transition zone :- It is of 50% saturated with water
  3. Transmission zone ;- Moisture content of soil is above the field capacity and below the saturation
  4. Wetting zone :-Moisture content is at or near the field capacity and moisture content decreases with depth.

Field capacity :-Volume of water the ground can hold...so lastly the saturation zone is useful for plant growth
